What's Wrong?

I wanted to add a comment on https://github.com/anthropics/claude-code/issues/1970, but that issue has been closed, so, opening a new one.
I'm experiencing something very similar, deadlock when claude is attempting the following command:

  Bash(ssh -i ~/.ssh/<cert-file> user@IP "ls -la /var/www/ispeak/api/data/ && head -200 /var/www/ispeak/api/data/arasaac_cache.json | head -100")                                            

I did the request manually and all good. Redirected it to a file.The response is big, 4 megabytes.

What Should Happen?

Well, claude should not hang :)

Error Messages/Logs

No response. Unresponsive. Esc doesn't work, Ctrl-C (twice fast) doesn't work.  Normal kill doesn't work.
"top" tells me it's using more than one entire core - my laptop fan is working hard ...

Only way to kill it is with -9

Steps to Reproduce

Bash(ssh -i ~/.ssh/cert-file user@IP "ls -la /var/www/ispeak/api/data/ && head -200 /var/www/ispeak/api/data/arasaac_cache.json | head -100")
